Title: Protection circuit of flyback transformer
Inventor: YAMAMOTO KAZUHIKO
IPC: H02H7/20
Filed: 1992-08-11
Abstract: PURPOSE:To quickly prevent the breakage of a flyback transformer by detecting an anomaly generated in the flyback transformer from the anomaly of the terminal voltage of an automatic brightness-limiting circuit on the secondary side of the flyback transformer and by stopping the horizontal oscillation of a horizontal oscillation circuit. CONSTITUTION:A +B power to be given to the primary-side winding L1 of a flyback transformer FBT turns on and off a transistor TrQ1 and generates a high voltage in a secondary-side winding L2 by a horizontal drive signal. The high-tension voltage of the L2 is applied to the anode of CRT, divided and supplied for focus and for screen, and also supplied to an automatic brightness-limiting circuit ABL from the terminal of the FRT. Further, the voltage of the FBT terminal 2 is also supplied to a protection circuit 1. When an anomaly occurs in any place of the FBT, the voltage of the output terminal 2 lowers to turn on TrQ10 and a horizontal oscillation circuit-stopping signal is outputted from a terminal 1a to stop the ON/OFF of the TrQ1. Thus, the breakage of the FBT is prevented quickly and surety.

Filed: 1991-09-17
Abstract: PURPOSE:To avoid the deterioration of the quality of a gate oxide film by a method wherein a reverse switching part which reverses or does not not reverse the contents stored in a plurality of memory cell layout blocks is provided. CONSTITUTION:A content stored in a memory cell layout block 1 which stores the contents of a ROM and further, is divided into a plurality of sections is read by a differential sensing amplifier 2 and supplied to reverse switching part 3. The reverse switching part 3 decides whether the read output of the differential sensing amplifier 2 is to be reversed or not in accordance with that the stored contents are reversed or not. In other words, if the contents stored in the section from which the outputted content is read are reversed, the outputted content is reversed and read and, if they are not, the outputted content is read as it is. As a result, a depletion type transistor can be eliminated, so that the area into which ions are implanted can be reduced. With this constitution, the deterioration of the quality of a gate oxide film can be avoided.

Title: Semiconductor photodetector
Inventor: MIKAWA TAKASHI
IPC: H01L31/107
Filed: 1988-09-20
Abstract: PURPOSE:To improve sensibility and usage by forming a transition region, in which band gap energy is changed, in a transition region from a well layer to a barrier layer and making approximately equal the threshold energy of ionization on the boundary of the barrier layer and the well layer. CONSTITUTION:A transition region C is shaped on a boundary transferring from a well layer B to a barrier layer A in the alternately laminated well layer B and barrier layer A. The transition region C is formed so that the height DELTAEv' of the energy barrier of a valence band on the boundary M of the well layer B and the transition region C is made approximately equal to the threshold energy Ei1 of ionization on the boundary L of the barrier layer A and the well layer B. That is, DELTAEv'=Ei1 holds. An energy band in the transition region C is changed gradually up to a boundary N with the barrier layer A from the boundary M with the well layer B. The threshold energy Ei1, Ei2 of ionization on the boundaries L, M is approximately equalized, thus generating ionization in both the boundaries L, M. Accordingly, the number of the laminating of the barrier layer A and the well layer B required for acquiring a specified multiplication factor is reduced by approximately half.

Abstract: PURPOSE:To keep off any worsening of steering stability in stabilizing a car attitude even at time of a wheel lock, etc., happening by holding each steering angle of rear wheels into such a size as just before being braked, in a car speed sensitive type four-wheel steering system. CONSTITUTION:A rear-wheel steering mechanism 2 steers each rear wheel 14 by means of rotation of a platelike cam body 7 being rotated by an electric motor 6 via a reduction gear 11 via a symmetrical pair of a turning roller-form cam followers 8, a slide bar 9 and a tie rod 12. A controller 15 controls the electric motor 6 on the basis of control information out of a car speed sensor 16 and a steering angle sensor 17, etc. In a four-wheel steering system performing steering control over the rear wheels 14 in use of a car speed detected value of the car speed sensor as one of control elements like this, a control method of the rear wheels is changed according to the case of braking time and vice versa. In brief, at time of braking, each steering angle of the rear wheels is made so as to have it kept in such a size as just before being braked. With this constitution, any improper motion in the rear wheels at time of being braked at turning is prevented from occurring, thus the worsening of steering stability is avoided.

Title: Magnetic disk device
Inventor: KORIYAMA HIROSHI
IPC: G11B21/02
Filed: 1989-09-12
Abstract: PURPOSE:To securely and stably position a magnetic head by bonding a metalic antiresonance mass substance in interposition of a viscoelastic material to a flat spring for supporting both ends of a center shaft for supporting rotatably the magnetic head via a bearing. CONSTITUTION:When a coil 9 is suddenly moved by call and write commands, the flat springs 7a and 7b for bearing a movable part, such as the magnetic head 1, etc., is oscillated due to the above exciting force. By this oscillation, a relative positional change between the head 1 and an information position of a magnetic disk 15, i.e., an off-track is generated. However, since the flat springs 7a and 7b are bonded with the massive body 6 via the viscoelastic material 16, this massive body 6 is worked with a phase difference from an oscillation period, and this oscillation energy is transmitted to the viscoelastic material 16 to be substituted for thermal energy, thus diminishing the oscillation of the flat springs 7a and 7b.
